2 Description of the product
2.1 Intended Use and Reasonably Foreseeable Misuse
The machine is a mobile, skid-mounted transformer with ineghrated power distribution panel board and receptacle
outlets. This system is designed to support power distribution application. The Eco Power Equipment SBP unit consists of
a skid with power distribution equipment mounted within a NEMA 3R tested sheet metal enclosure.
This machine is intended for prime rated power requirements and has been designed to operate 24/7. This equipment is
also intended for the purpose of supplying electrical power to connected loads. Refer to the product rating plate for the
output voltage and frequency of the unit, and for the maximum output power limit of the panel.
This machine has been designed and built strictly for the intended use described above. Using the machine for any other
purpose could permanently damage the machine or seriously injure the operator or other persons in the area. Machine
damage caused by misuse is not covered under warranty.
The following are some examples of misuse:
Connecting a load that has voltage and frequency requirements that are incompatible with the rating
Overloading the machine with a device that draws excessive power during either continuous running or start-up
Operating the device in a manner that is inconsistent with all federal, provincial and local codes and regulations
Operating the machine outside of factory specifications
Operating the machine in a manner inconsistent with all warnings found on the machine and in the Operator’s Manual
This machine has been designed and built in accordance with the latest Canadian safety standards. It has been
engineered to eliminate hazards as far as practicable and to increase operator safety through protective guards and
labeling. However, some risks may remain even after protective measures have been taken. They are called residual risks.
On this machine, they may include exposure to:
Electric shock and arc flash
To protect yourself and others, make sure you thoroughly read and understand the safety information presented in this
manual before operating the machine

2.2 Maintenance
Eco Power Equipment Recommends all customers integrate a routine maintenance for all mobile power distribution
equipment. This equipment has been designed to provide mobile power distribution and as such we recommend our
customer implement a routine maintenance program:
1. Torque Check Procedure: All mobile power distribution should undergo regular torquing procedures before use.
This procedure should be developed based on the movement and usage of the equipment. With regular
checking and verification of critical connection points, here are some examples:
a. Hubbell Bus Tab Connection Points: 107-inch lb (9 ft-lb)
b. MCCB Tab to Breaker Bolts: 288 in-lbs (24 ft-lb)
c. MCCB and other items have torque ratings directly labelled on the device
2. Thermal Inspection: Abnormal heating associated with high resistance or excessive current flow is the main
cause of many problems in electrical systems. Infrared thermography allows us to see these invisible thermal
signatures of impending damage before the damage occurs. When current flows through an electric circuit, part
of the electrical energy is converted into heat energy. This is normal. But, if there is an abnormally high
resistance in the circuit or abnormally high current flow, abnormally high heat is generated which is wasteful,
potentially damaging and not normal.
2.3 Setup Process
The setup and deployment process involved for the SBP-XFMR series power distribution panel involves locating the unit
on a level, suitable terrain, connecting earth ground, and connecting electrical distribution.
Before using the unit, be sure to read and understand all of the instructions. This equipment was designed for specific
applications; DO NOT modify or use this equipment for any application other than which it was designed for.
Equipment operated improperly or by untrained personnel can be dangerous.
Before using a unit visually inspect the unit for damage. A complete visual inspection of all power distribution
connections.
Equipment Spacing:
Eco Power Equipment recommends that SBP-XFMR type power transformers be mounted so that there is an air space of
no less than 305 mm (12”) between the enclosure and any adjacent wall unless otherwise marked. Furthermore, it is
recommended that a minimum air space of 610 mm (24”) be allowed above the transformer for adequate cooling. A
minimum working space of 762 mm (30”) is recommended for all removable access panels that provide access to
connections, and any renewable or adjustable parts / accessories. If the transformer must be located near a combustible
surface / wall, the minimum clearance established by the Local Electrical Code and Fire Marshal should be maintained.
11

Location and Enviroment
Dry type transformers should be located such that they comply with all applicable local safety and electrical codes. It
should not interfere with the normal movement of personnel, equipment and material and should not expose the
transformer to potential damage from cranes or other moving equipment.
Enclosures are intended for use in secured areas, generally not accessible to unauthorized or untrained persons.
Transformers with open bottom enclosures, or with bottom ventilation openings should not be installed on or over
combustible surfaces.
Outdoor ventilated units should ideally be located such that nearby buildings or landscape features can help reduce
windblown dust, rain or snow from entering the enclosure.
Transformers to be installed at altitudes greater than 1,000 m (3,300 ft.) above sea leave, or in ambient temperatures
exceeding a maximum average of 30 ⁰C and a maximum peak temperature of 40⁰C must be specifically designed for these
environmental conditions to operate correctly

2.4 How to Use the Product
2.4.1 Safety information
●Only qualified technicians should attempt to work on electrical equipment.
●Always wear protective clothing and footwear when working on or around the transformer.
●Any person with a pacemaker, metal implant, or jewelry should not come within 10 feet of the transformer
enclosure while it is in operation.
●The use of electrical safety, arc flash safety grounding, and lockout/tagout procedures should always be
followed to ensure personal safety when installing, servicing and uninstalling electrical equipment.
●Never energize a transformer if it appears to be damaged.
●Never lift anything over head or over top of other persons.
●Generally, the voltage required will be the rated voltage times the per unit impedance time the percentage
of current required. The winding temperature should not be allowed to exceed the average winding
temperature rise or 100 ⁰C, whichever is lower. Refer to ANSI/IEEE C57.94
●In the event of a fire, do not use water to extinguish the flames. Use a suitable quenching agent such as,
CO2.
●Terminals are for electrical loading only. Wherever possible, use flexible connectors to avoid mechanical
strain on terminal pads.
●Always inspect the unit to ensure that nothing has entered the enclosure or unit that might create a safety
hazard such as debris, rodents, animals, etc. This is more likely to occur if the transformer has been stored
for any length of time.
●Make sure all power supplies are disconnected and properly grounded before attempting to work on the
transformer or inside of the control box.
●Do not make any connections that are not authorized by the nameplate or the connection diagram.
●Do not enter the cabinet or stick objects into the unit when energized. This could result in injury or death.
●High voltage is present in the system while on, never attempt to service the electrical system while the
engine is on, or the system is on - qualified technicians should only setup this equipment
●Do not a unit if there are signs of wear or damage
●Never permit anyone to operate the unit without proper training
●No supply cables should come in contact with the core or any live part except the terminal that it is intended
for. Ensure that minimum electrical clearances are maintained. (Refer to Table 1, Section 7.4)
●Never modify equipment without the written consent of Eco Power Equipment
Transformer Specific Details
●User installed cables must be kept as far away from coils and top clamps as possible. Refer to the Table 1
below for recommended minimum electrical clearance when performing final check. You should only make
those connections specified by the nameplate or connection diagram. Be sure to check all tap jumpers for
correct location and torque.
●Some tap connections and other joints involve bare aluminum or copper. If it is necessary to change taps or
assemble a joint of bare aluminum or copper, lightly clean the contact surfaces. Once the contact areas have
14

been abraded, assemble the parts and tighten securely. Always use two wrenches when breaking or making
joints to prevent damage to parts.
Table 2 below summarizes the recommended torque values for the different types of bolted electrical connections found
on dry-type transformers. All electrical connections should be checked prior to the energization of a unit.
Tap connections are typically provided to adjust for difference between nominal and tested incoming voltage values.
Standard units have taps located on the face of each phase coil (See figure 9). Unless specifically instructed otherwise,
transformer are shipped with the tap connection made for the nominal voltage. The taps are marked with letters or
numbers which correspond to the markings on the nameplate schematic. When changing taps, the following instructions
should be followed:
1. De-energize the transformer.
2. Short-circuit and ground the HV and LV terminals.
3. Locate the tap jumpers.
4. Loosen the hardware on the tap jumpers.
5. Remove the tap jumper and move the connection to the desired tap on each phase. (All coils must have identical tap
setting).
15

6. Verify all coils are connected at identical taps.
7. Torque the taps connections to the recommended values per Table 2, Section 7.5.
8. Remove the shorting connection on the HV and LV terminals.
9. Inspect the transformer to ensure that no tools or other objects have been left in the vicinity of the transformer
10. Replace all access panels, and re-energize the transformer
When cable connections are required, conductors suitable for at least 90⁰C should be used. Connections should be made
and supported such that they do not stress the terminals with the weight of the cables while still allowing for expansion
and contraction. The minimum electrical clearances to the core & coil per Table 1 in Section 7.4 should be maintained
and all connections should be torqued to the recommended values per Table 2 in Section 7.5.
Note: Top cable entry is not permitted in the main transformer compartment in accordance with CSA C22.2 No.47. If the
enclosure is fitted with air terminal chambers barriered off from the main compartment, then cables may be brought
into the top of these terminal chambers. Please contact Rex Power Magnetics or refer to the outline drawings supplied at
the order stage for instructions on appropriate cable entry locations.
Anti-vibration Pads
Dry type power transformers supplied as core & coils, or installed in an open bottom enclosure are supplied with
standard neoprene anti-vibration pads to be positioned underneath the core and coil base channel assembly. These
anti-vibration pads reduce the transfer or vibration and noise from the transformer core to the mounting surface. Refer
to figure 6 for proper location of these
pads.
16

Loading:
When energizing a transformer from a cold start, it is preferable to slowly increase the load while monitoring current,
voltage and load levels. If this is not possible, full load may be applied with caution. Note: When energizing a dry type
transformer for the first time, some smoke and vapor may appear during the first few hours of operation. This is normal,
and should dissipate within a few hours.
Parallel Operation:
Transformer may be operated in parallel to supply larger load as long as their polarity/phase shift, rated voltage,
frequency, impedance and turns ratios are the same. If these parameters differ, circulating currents will flow in the circuit
loop between the parallel units. The greater the difference between these parameters, the larger the magnitude of the
circulating current. The difference in impedance should not exceed 10% and the remaining parameters should be
identical. When specifying a transformer to be operated in parallel with an existing unit, the precise parameters of the
existing units need to be noted.
Voltage Selector Switch
●Always set to the appropriate voltage for your application, these units have been factory set to 480V and 600V
tap positions - review on each installation and commissioning
●Note the this is a multie tap transformer, so it is possible to fine tune output voltage if your applications requires
changes
